Great value at a great price
I bought mine from Amazon, but for the price I paid and the features and sound quality I got I'm extremely happy. It looks good, is easy to setup, and it sounds great. The bass is also good quality as well. This is the perfect upgrade from using the TV speakers.

Almost returned glad I didn't
I've only had my set up for a couple of days, and I had problems right from the start. The sound didn't since, the soundbar and tv both came on at the same time and I got the wrong power cord to plug in the sub. I was going to return it the next day, but played with it that night.
I found that if I used the able remote to turn on the tv and soundbar they would both play together. Using the tv remote to cut on the tv would make the bar work while the tv was silent. I then went into the settings on the tv (tcl and was able to adjust the delay and since the voices. Problem solved!
Luckily I had a old computer cord that plugged into the sub so it's working fine.
Like I said I almost returned the unit, but honestly I was just too afraid I would have the same issues with a unit that didn't sound as good. I could complain about the power cord, but the other problems were not the sound bars fault and could happen with the next one.

Great sound for the price.
We have had the S2 for about 6 months. Sounds great for size. It was easy to set up and to operate. I have no problem recommending it to anyone.

Ok soundbar
The sound isn't as good as I thought it would be. My wife thinks the TV sounds better than the soundbar.

Terrible Connection Issues
Not always recognized as being plugged in, when it does, randomly will disconnect, turn off tv and connection is lost, sound lags behind video and changing that option completely disconnects the sound bar and won’t recognize. Returning the product to Best Buy.

Great Sound, horrible connection problems!!!
Buyer Beware! This soundbar for $150 is amazing in sound quality. The sub is great and the bar fills the room with sound. However I’ve had nothing but connection issues. No matter what the sound bar does not sync perfectly with the tv. It’s always half a second off making it look like I’m watching something dubbed all the time. Only with the cable box does this happen. The PS4 syncs just fine. I also had to dig and do a bunch of research just to hook it up. The instructions were horrible and the remote is useless.

Great sound. My only thing is that the remote could be a bit sturdier.

Can’t control soundbar with my tv remotes although I could yesterday. Instructions suggest I can but they don’t elaborate. Subwoofer is so much weaker than in BestBuy I wondered if it was on. Instructions say I can use HDMI ARC cable, but I still must connect the Optical cable.
Returning tomorrow

Great Set
The speakers were very easy to connect with my TV and work as expected. The wireless subwoofer was already paired with the soundbar and works great, I love the extra thump. Overall a good value with very good performance.

can I add rear wireless speakers?
A shopper on Dec 23, 2019
  Thanks for your inquiry. The Signa S2 Sound Bar has no provisions for surround speakers wired or wireless.
do i connect both HDMI and optical cables?
A shopper on Dec 15, 2018
  Only one is required. HDMI ARC is preferred if your TV has a compatible input.
